`IMPROVLMEN'I IN HYDRAULIC ENGINS.

@he .Stimmt numb tu in that trttirs utrnt mit making pnt rf the smut TO ALL WHOM I'I MAY CONCERN:

Be it known that I, MAnLoN EVRETT, ot' the village of Kalamazoo, and State of Michigan, have invented vcertain new and useful Improvements in Water Engines;` and I do hereby declare that the following is afull, clearfnnd exact description of the same, reference being Ahad to the accompanying drawings, and to the letters of4 reference marked thereon, which accompany this application, and form a part the rcof.`

The nature of my invention consists of arranging two force and lift-pumps side by'side, so connected and operated as that the piston of one pump shall, by its motion, work the supply-valve ofthe other,.and vice versa, thus producing an automatic and continuous motion. In the drawings- Plate 1 Figure 1, is a top view of my double waterengine.

Plate 2, Figure 1, is a bottcm'view of the same.

Plate 3, Figure'l, is a vertical section of one pump. v

Plate 4, Figure 1, is a planA of anfescillating valve having three longitudinal bars or divisions.`

Figure 2 is'a plan'oi` an oscillating valve having twobars or divisions. i

Figure 3 showsa horizontal sectional view of said valves connected with the water-chest.

Figure 4 is a sectional horizontal view of the oscillating valves, `watei-ehest, and side pipes, and their connection with the cylinders. l i

In plate 1, iig. 1, A A are air-chambers surmountingthe cylinders B B', and connected therewith by an opening at their junction. C1 G2 Q3 C4 are tubular receivers, attached to and connected with the cylindersB B by means of side pipes Dl l)2 D? D4. The arm-rods G G' are attached to the :ylinders BIB by the lugs Il I2, through which they move. The arms Hl H2 H3 H4 are secured to the rods G Gr', and are actuated by them'.

The lugs Il I2 I3 I* serve to connect the cylinders B B' with the valve-cylinders E E', and are made hollow. l F is a water-chamber ot' circular form, and connected withV the valve-cylinders E E' by suitable openings, as seen` .in iig. 4, plate 4. F is the supply pipe, through which water is conducted to'thc water-chest. In g. 1, plateA 2, J J J J are suction-valves, through which water is 'drawn for distribution, attached to the lower side ofgthe ends of the receivers C1 CZ C3 C". The valve-armsL L are attached to the valve-stems ZZ, andturn the oscillating valves P I",` plate 4, gs. 1 and 2, backwards and forwards as they are operated by the arm-rods G G', by means i et' pins or other suitable device. The arms L L are secured in theirproper position upon the valve-stem Zby means of the set-screws a a. y

In iig. 1, plate 3, M is a piston-rod, workingin the centre of the cylinder B, through piston-heads o o, pro

' videdwith stuing-boxes l d', said `piston-rod being provided at each end with a plunger, e, working in the plunger-tubes ff. The openings c c conduct the water raised up through the suction-valve chambers J J, and propelled by the plungers e e, through the openings g g, into the air-chamber A; and from thencethrough the discharge pipe h. The piston N is situated in the centre of the cylinder B, and operated by the piston-rod M, A 'to which it is attached by the hubs jj and the jam-nuts 7c lc. lThe nuts r r are adjustable on'the piston-rod M, and serve to regulate the throwo f the arms Izl1 H2 H3 H4, the inner ends of which terminate ,in loops, through which the piston-'red passes, working loosely. z' z' are the legs supporting the frame upon which .the apparatus rests.

In iig. 1, plate 4, is shown the oscillating valve P, the head of which isV circular, and the circumference,

:composed of three longitudinal bars, ush with the circle of the heads,and the bars divided by semicircular recesses, as shown at mm m, iig. 3. I", fig. 2, plate 4, is a second oscillating valve, similar in construction to P, fig. 1, with the exception of having only two bars and two recesses, asseen at n. u, tig. 3, platel. These lvalves are each provided with alstem, Z Zto which the arms L L are attached, as seenin tig. `1, plate 2.

'In tig. 4, plate 4, o `is the pipe conductingthe water from the valve P' tothe cylinder B, whilep is a similar pipe, leading from the cylinder B' to the recess in the valve P, and thence to t'he discharge-port q of the valve= cylinder E.. The vpipe s conducts the water from the valve P to the cylinder B,lwhile` thetpipe s conducts the water from the cylinder I3 'to the discharge-port q', through the recess of the valveP', the direction of the curi rents of water being shown byl the arrows The operatlonof my engine is substantially as follows: The water-chest F and valve-cylinders E E' being filled with Water under full pressure of the column, and the ingress-port I of the cylinder 'B being open, the water flows behind piston N, causing its stroke, in which the nut r on the piston-rod M, when seid piston is inishng its stroke, to carry the crm Hl fer enough to turn the valve P by mea-ns of the valve-:mn L, operated by the arm-rod G. The water then Hows into cylinder B behind its piston, producing the stroke of said piston, and which, nearly at the finish, carries the nut r forward, striking the arm H3, which, by means of the ernia-od G and valve-ermL, turns the oscillating velve P, and the water is thus turnedinto cylinder B, producing the return stroke of the piston in said cylinder, seid piston carrying with it, by means of the nut s', the erin ofthe vulve P; and, while piston N is making its stroke in return, the water which was in cylinder B is being discharged through the port g of valve-cylinder E. The egress and ingress-ports of the vulve-cylinders E and E are opened simultaneously, respectively; und, as the piston moves backwards and forwards, the waiter which is behind the plungers e e is raised up into the receivers Cl C C C, and the water which is foiwnrdof the plungers is forced up into the oir-chambers A A', und is prevented from returning by the check-valves placed in the openings g g, while the water in the receivers is prevented from returning to the well or spring by the suctionvalves b b I7 11.

It will be seen that the pistons folloiv each other in their reciprocating mot-ions, the one remaining at rest until the other has nearly completed its stroke, which peculiar movement thus secures regular and continuous motion in the engine,.ond it can only be stopped by extraneous mutter coming in contact with its working ports. Having thus fully described my seid invention, what I claim :ts new, and desire to secure by Letters Patent, is

The valves P and P', the valve-arms L L, and the arms HL H2 H3 H4, in combination with the erin-rods G G and piston-rod M, all :wronged and operated es and for the purposes herein set forth. Y
